LOOM-SHUTTLE.

' yraterrci, April so, 1907.

d diepen-.mt narrateur 24,1906'. serai No. 344,815.

l a citizen of the United States, and a resident specified type.

of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Loom-Shuttles, of which the following description, in connection with the ac` companying drawings, is a specification, like letters on the drawing representing like parts.

This invention relates to loom-shuttles used in iooins of the automatic filling-replenishing type, such, for instance, as shown in United States Patent No. 529940, granted to Northrop November 27, 1894, wherein a fresh filling-carri er or bobbin is automatically inserted in the running shuttle at the proper time.

The head of the Afilling-carrier is engaged and held in position by a holder provided with spring-jaws, the annulady-ribbed head being inserted between. them, and an inclined directing-plate or guide is located between the jaws, to direct the head into proper position to be engaged by the jaws.

It has been found that the impact of the head of an incoming filling-carrier upon the inclined guide tends'to push the bent back upper end thereof toward the adjacent end of the shuttle, into the wood of the shuttlebody,.so that "the positioning of the head with relation to the jaws is at times faulty.

In my present invention I'have provided a simple and positive lock between the holder and the u iper end of the guide, so that there can be no longitudinal movement of the guide with relation to the holder, thereby overcomino' the objection referred to.

lIfhe novel features of my invention will be fully described in the subjoine'd specification and particularly pointed out in the following claims.

Figure 1 is a top plan view of the holding end of a loom-'shuttle of the type referred to, `with one embodiment of my present invention applied thereto, the shuttle-body being partlyl broken out; F ig. 2 is a partial longitudinal section on the line 2 2, Fig. 1.

,The shuttle-body A having a longitudinal opening A therein open from top to bottom of the body to receive the filling-carrier and permit the passage therethrough when ejected, is of usual construction in shuttles of the At one end of the opening the body is recessed at 1 to receive the holder 2, made as a metal block having parallel sides, and flat, parallel top and bottom faces, the front end of the holder having two spring jaws 3, extended into the opening A.

, Said jaws are preferably grooved, at 4, to receive the usual annular projections,-ribs or rinl s on the head of the filling-carrier, which is t ereby engaged and securely held in position in the opening A.

The inclined directing-plate or guide 5, which assists in directing the filling-carrier into position, is located between the jaws and preferablyis made of resilient metal, as usual, the lower end of the guide being bent back at 6 to extend beneath the holder 2,'between it and the bottom of the recess' 1, see Fig. 2. The upper end of the guide is bent down at 7, and then rearwardly extended,\ at S, u on the top of the holder, and in practice t e side edges of the extension enter grooves, as 1X, see Fig. 1, formed in the side-walls of the recess 1.

The construction thus far described is not of my invention, and is well-known to those skilled in the art.

Heretofore the end of the extension 8 has been bent down to form a lip 9, as herein, which fitted over a transverse shoulder on the top of the holder, and between it and the outer end of the recess 1. When so constructed, however, the impact of the head of the incoming filling-carrier on the guide .5 tends to forcel rearward the extension 8 against and into the wood forming the end of the recess in the shuttle-body, so that the guide becomes loose and gives so much that the filling-carrier is not properly positioned between the jaws 3. In accordance with my invention I obviate this objection by forming a transverse slot 10 in the top of the holder, into which slot the lip 9 enters, thereby forming a positive lock between the holder and the guide, so that the latter cannot work loose or have any longitudinal play relative v lto the holder. Manifestly the end of the recess 1 has no function in resisting the thrust of the extension S, as it is taken up by the rear wall ofthe slot 10, and thel single screw 11 passed through the holder into the walls of the shuttle-body retains the holder and guide in place.

Having fully described my invention, what IOO I claim as new and desire to secure by Lettersl Patent is 1. Aloom-shnttle having an opening there- 1 in, a holder fixedly mounted in the shnttle-l l 5 body at one end ofthe o 'ening and provided l with jaws to engage the ead of a filling-oar- 4 rief, an inclined guide between the jaws and having a rearward extension projecting above the' holder, and a positive lock between the g lattein and lthe extension and independent of the shuttle-body to prevent movement ofthe guide backward or forward relatively to the holder. j 2. A holder having a pair of spring-jaws 'to I 5; engage the end of :i iillingmarrier, said holder g having on its top a transverse slot, a cooper'- ating guide lnchned between the jaws and having its ends bent back'i'to 'receive between .them the holder,

'the upper one of said ends having a downtuined lip to enter the slot in the\holder and thereby positively lock the guidethereta l In; testirnony whereof, 1 have signed my name to this speelfieation, 1n the presence of two subscribing witnesses.
